PURPOSE: A waterproofing structure for a concrete structure is provided to simplify a structure to remove gas from a waterproofing object and to protect the waterproofing object from fire. CONSTITUTION: A waterproofing structure for a concrete structure comprises a waterproofing layer (W) and a waterproofing finishing cover (90). The waterproofing layer covers a base surface (2) and a wall surface (4). A sheet waterproofing layer (W-1) forming a degasing path is installed between the bottom surface and the wall surface. The waterproofing finishing cover is installed on the wall surface and covers the edge part of the waterproofing layer covering the wall surface in order to prevent foreign substances from permeating into the degasing path. The sheet waterproofing layer is comprised of a plurality of waterproofing sheets, and the waterproofing sheets include a sheet main body and a flame retarding material.
